"Don't know where you copied al that from,but was looking at something like this,
The pc i'm on right now,

see? Very simple layout.
Anyway,seems your ram sticks are in A1+B1 where recommended by Asus it says with two sticks to use A2+B2. Since the ram works at a voltage of 1.2V is there still room to add abit.
Try it with three sticks,use the ones in the pc right now in A1+A2 (two slots closest to the cpu) and add the third stick in the B2 slot (furthest from the cpu).Add abit of voltage to the Dram voltage so set it ti 1,25V at first,means adding 0.05V,see if this will help.Can go up to 1.35V by adding 0.05V each time.
Also set the SOC voltage to 1.1V for some more stability on the memory controller.Can't find this one in that summarily manual of the motherboard so check if it's there.
Might also see if setting the OC on the cpu to 3.9ghz gives more stability on the ram as well.Can first try at stock settings and get the ram stable,then try overclocking again.
If none of these steps help i'm probably at the end of what i can recommend and is the third stick just not compatibel.
